Please help with pda!!!!!!!

[gersrt]

Hi

I need some help I have a pda that the sound packed in on.

I opened it up and checked the little loud speaker inside and it work fine.

It doesn't seem to be getting any power from the circuit board.

The headphone socket works fine and I can get sound from that.

So what I wanted to do was run a couple of little wires from the inside of the headphone socket to run the little internal loudspeaker.

Any way as I found out there doesn't seem to be enough power coming from the headphone socket and the loudspeaker is very low.

Any ideas how I can increase the volume from the loudspeaker please.

I really need to get this to work.

Thanks

Please have a look at page one of this document attached.

Thank u

That's a comparator which is totally useless as an audio amplifier.

You want something like the LM386 for a small audio amplifier.

Before you do anything though, I would check that the speaker hasn't being disabled in the software settings.

The schematic is shown in the datasheet. It tells you how to wire it up.
